ramkrishna.s.vasudevan commented on HBASE-14643: ------------------------------------------------ +1 on patch. Splits can be some what more faster now I think after this goes in. > Avoid Splits from once again opening a closed reader for fetching the first > and last key > ---------------------------------------------------------------------------------------- > > Key: HBASE-14643 > URL: https://issues.apache.org/jira/browse/HBASE-14643 > Project: HBase > Issue Type: Improvement > Components: regionserver > Affects Versions: 2.0.0 > Reporter: ramkrishna.s.vasudevan > Assignee: Heng Chen > Attachments: HBASE-14643.patch, HBASE-14643_v1.patch, > HBASE-14643_v2.patch, HBASE-14643_v3.patch, HBASE-14643_v4.patch > > > Currently split flow is such that we close the parent region and all its > store file readers are also closed. After that inorder to split the > reference files we need the first and last keys for which once again open the > readers on those store files. This could be costlier operation considering > the fact that it has to contact the HDFS for this close and open operation. > This JIRA is to see if we can improve this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
